- W4313463877 abstract "Abstract The PHENotype SIMulator, is a systems biology tool, which leverages available transcriptomic and proteomic databases to model of SARS-CoV-2 host-infection in silico. PHENSIM can determine the viral effects on cellular host-immune responses, which we recently applied to in silico drug repurposing for COVID-19. There is a clear importance of previously imprinted viral infections on the host-immune response against SARS-CoV2. In this study we explore the potential clinical applicability of PHENSIM in addressing co-infection of SARS-CoV2 (SCoV2) and human rhinovirus (HRV), or SCoV2 and Influenza A Virus (IAV). We leveraged PHENSIM to simulate HRV-infection of A549 lung alveolar cells at 24hours in silico, yielding comparable cellular transcriptomic signatures as previously published for in vitro HRV-infection, including antiviral and inflammatory gene transcriptomics. Next, we simulated viral co-infection of HRV/SCoV2 or IAV/SCoV2 using PHENSIM, and assessed co-infection effects in silico. Similar to recent in vitro studies, our in silico results indicated HRV-infection prior to SCoV2 exposure induced ISG responses and downregulated SCoV2 transcriptomic activity. Further analysis revealed several key SCoV2 affected pathways, including IFN Type-I & -III and MHC-II pathways, to be negatively affected by HRV-infection. In contrast, co-infection with IAV and SCoV2 resulted in overall increased SCoV2 transcriptomic activity. Our PHENSIM results confirm HRV-imprinted downmodulation of SARS-CoV2 activity and the importance of timely IFN pathway activation for effective immune response and viral clearance. Identified anti-correlating pathways are of interest for therapeutic targeting and effective drug development.
